ABE — Docker Specification

Objetivo

Permitir arrancar todo el proyecto (backend + frontend) con un solo comando: docker-compose up --build

Backend Dockerfile (raíz del proyecto)

FROM node:20-alpine
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build
EXPOSE 3001
CMD ["node", "dist/server/index.js"]

Frontend Dockerfile (frontend/Dockerfile)

Usa build multistage: primero compila con Node, luego sirve con nginx.

FROM node:20-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build

FROM nginx:alpine
COPY --from=builder /app/dist /usr/share/nginx/html
COPY nginx.conf /etc/nginx/conf.d/default.conf
EXPOSE 80

nginx.conf (frontend/nginx.conf)

Necesario para que React Router funcione correctamente (todas las rutas apuntan a index.html):

server {
    listen 80;
    root /usr/share/nginx/html;
    index index.html;

    location / {
        try_files $uri $uri/ /index.html;
    }

    location /api {
        proxy_pass http://backend:3001;
    }

    location /socket.io {
        proxy_pass http://backend:3001;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

docker-compose.yml (raíz)

  frontend:
    build:
      context: ./frontend
      dockerfile: Dockerfile
    ports:
      - "5173:80"
    depends_on:
      - backend
    networks:

networks:
  abe-network:
    driver: bridge

Notas importantes

El frontend en producción (nginx) hace proxy de /api y /socket.io al backend
Los volúmenes reports/ y logs/ persisten datos entre reinicios del contenedor
El frontend se accede en http://localhost:5173
El backend se accede en http://localhost:3001
